What timepiece has the most moving parts? And which the fewest?

I would guess this clock has the most and this one has the fewest.

An hourglass? There’s lots o’ moving sand in there.

Oooooh. Nice.

Hourglass has the most, sundial has the least.

Specifically, this hourglass, the largest using actual sand (over a ton). It measures an entire year.

You could actually make the argument that a water clock has fewer moving parts than a sundial, since the sundial has two: the Earth and the Sun, whereas the water clock has only the water.

You know, I was thinking, too, that just about any digital timepiece would have zero moving parts. True?

Well, it does have the oscillating quartz crystal. That is movement.

Well.
The Hourglass has the most because it’s full of sand.
The one with the fewest is a sundial because it only has one.

thankyou AQA

Thinking about it, I guess I should back off from my “sundial has two moving parts” assertion; for all practical purposes, the Sun could be considered stationary. But yeah, seems like the sundial, the water clock, and the quartz digital could all be considered to have only one moving part.

The night sky has the most moving parts. The sun, our own personal star, has the least.

Is Harpy a computer disguised as… Harpy?

ah. nice one katawa.
